This invention relates to new and useful improvements in a means for the v propulsion of a ship or the like.

The invention has for anV object the con struction of a cam element for lattachment uponthe `side of ship, and a casing rotatively supported outside of said cam element and having blades pivotallymounted atv one of their ends and connected with pins engaging in said cam to cause said blades to. move into operative positions as the casing turns.

Furthermore,fas another object- ,ofthis invention, it is proposed to construct the parts in a manner which will allow adjustment of theiamplitude of motion of the blade. Y

The invention still further proposes the construction ofa device of the class described which is of simple, durable construction, de-

pendable in use and eiicient in operation and which can be manufactured Land "sold at a yreasonable cost.

For further comprehension. of the invention, and of the objects and, advantages'thereof, reference will'be had to the following description and accompanying drawing, and to the appended claims in which the various vnovel features of theinvention are more par- 40j withl the cover plate removed, looking in the ticularly set forth. u

A ship 10 has been illustrated with plu-V4 this invention, mounted on the sidesthereof below the waterflevel: Each of the propulv sion means comprises an element 12 vin the formlof a block having a suitable size of cam y groove, 13 and for attaehmentlupon the sidev 'of the ship.` A shaft 14 vpasses through the cam element and is connected with'some source of rotations such as motors 15'. 'f l v A casing 16V is located to thefrontof 4Athek u element 12 VVand-is xed upon the shaft 14so 'as to turnin unison with the shaft. The casing 16 comprises a: pair of spaced discs clearly shown in Fig. 5,. Y Each'of these discs has a vring Vl'rotatively mounted on .its periphery andi-set screws 18 serve to hold these. i rings in various rotative positions. A plurality of'plates 19 are arranged in end to end relation around the'rings 17 and arepivotally mountedat their rearl ends 20 uponlthe rings.

tweenthe discs' 16., of these slides is providedwith wheels 22 atits edges engaging rality of propulsion meansl llaccordingito i a'track 23 mounted upon oneJ` of the discsv i 16.v A peg 24 ismounted upon-eachiof the slides and these pegs project throughradial slots-25 in one ofthe discs 16 and at their outer ends carry rollers 26 engaginginthe cam groov'e13.v 'i

Connecting rods 27 are'pivotally mounted tracks 531 longitudinallyalong the lengths Vat one of their ends upon the slides-21 bythe of the blades 19. A'set screw 32 is mountedi in each of the blades and act against theKA slide 31 for holding the latter in any desired adjusted position.

Therings 17 have internal flanges V`33.,en gaging peripheral grooves in the disc 16 to accomplish the rotative mounting of .theV

rings upon the flanges. The .blades 19 have Y portions 34 which extend beyond one `of the dises 16 solas to provide greater width and .ship forwards. Fig. l4 clearly showsthe positions in which the blades open. The blades Slides 21 are arranged to slide radiallybe-A 59' ends-of the connecting yrods adjustably alongv -lthe lengths otsaid blades.
